Google is almost correct. The transmissions are the same designation but there are differences. One big one is that the build date of your truck makes a big difference. An early year build is going to be OBD I while the later builds are OBD II compliant.
The catch there is that the earlier transmission does not have the correct internal controls or the range sensor pieces to work with the computer in the 1995. That switch tells the ECM what gear the transmission is in so the controller can function. Without it you will not have a working automatic. It may not operate properly even with the switch installed because of other changes.
